Abstract Crop production and quality safety system have the potential to nurture human health improve environmental sustainability. Providing a growing global population with sufficient healthy food is an immediate challenge. However, this largely depends on spraying of agrochemicals. leaves are covered different microstructures, exhibiting distinct hydrophilic, hydrophobic, or even superhydrophobic wetting characteristics, thus leading various deposition difficulties sprayed droplets. Here, relationship between wettability surface microstructure in crop from biological interfacial structural perspectives systematically demonstrated. A relational model proposed which complex microstructures lead stronger leaf hydrophobicity. And adding surfactant faster dynamically migrating velocity reducing droplet size can agrochemical precise deposition. These contribute toward highly accurate efficient targeted applications fewer agrochemicals use promote sustainable models eco‐friendly agriculture systems.
